1984, George Orwell
"He wondered, as he had many times wondered before, whether he himself was a lunatic. Perhaps a lunatic was simply a minority of one."

"It paid, she said; it was camouflage. If you kept the small rules you could break the big ones" p. 129
"O' Brien's manner became less severe. He resettled his spectacles thoughtfully, and took a pace or two up and down. When he spoke his voice was gentle and patient. He had the air of doctor, a teacher, even a priest, anxious to explain and persuade rather than to punish" p. 245
